Abstract
Abstract The acrylamide monomer, N -(4-bromophenyl)-2-methacrylamide (BrPMAAm) has been synthesized by reacting 4-bromoaniline with methacryloyl chloride in the presence of triethylamine(NR 3 ) at 0–5 °C. Copolymers of N -(4-bromophenyl)-2-methacrylamide (BrPMAAm), with glycidyl methacrylate (GMA) were synthesized in 1,4-dioxane solution at 70 ± 1 °C using 2,2′-azobisisobutyronitrile (AIBN) as an initiator with different monomer-to-monomer ratios in the feed. The copolymers were characterized by FTIR, 1 H-and 13 C NMR spectroscopy. The copolymer composition was evaluated by nitrogen content (N for BrPMAAm-units) in polymers led to the determination of reactivity ratios. The monomer reactivity ratios for BrPMAAm (M 1 )–GMA (M 2 ) pair were determined by the application of conventional linearization methods such as Fineman–Ross ( r 1 = 0.2893; r 2 = 0.7114), Kelen–Tudos ( r 1 = 0.3361; r 2 = 0.8645) and extended Kelen–Tudos ( r 1 = 0.3096; r 2 = 0.8577) as well as by a non-linear error variables model (EVM) method using a computer program, RREVM ( r 1 = 0.3453; r 2 = 0.8606). The mean sequence lengths determination indicated that the copolymer was statistically in nature. The polydispersity indices of the polymers determined using gel permeation chromatography suggest a strong tendency for chain termination by disproportionation. Thermal decomposition of the polymers occurred in three stages in the temperature range of 100–500 °C and the glass transition temperature ( T g ) range of 94–165 °C.
